The inherent stochasticity in many nano-scale devices makes them prospective candidates for low-power computations. Such devices have been demonstrated to exhibit probabilistic switching between two stable states to achieve stochastic behavior. Recently, superparamagnetic nanomagnets (having low energy barrier EB ∼ 1kT ) have shown promise of achieving stochastic switching at GHz rates, with ve...

The recent increase in modular pulsed power systems has amplified the potential of optically controlled discharges where stringent synchronization in time is required. This interest has lead to new switching applications and concepts as well as new understanding of the switching process from a fundamental standpoint. The increasing diversity of wavelengths available has necessitated a modificat...

Voltage-controlled resistive switching in various gap systems on SiO2 substrates is reported. The nanoscale-sized gaps are made by several means using different materials including metals, semiconductors, and amorphous carbon. The switching site is further reduced in size by using multiwalled carbon nanotubes and single-walled carbon nanotubes. The switching in all the gap systems shares the sa...

We report the experimental observation of periodic switching topological edge states between two dimerized fs-laser written waveguide arrays. Switching occurs due to overlap modal fields from forbidden gap, when they are simultaneously present in arrays brought into close proximity. found that phenomenon for both strongly and weakly localized rate increases with decreasing spacing When contact ...
